Benefits of technology

The patent falls under a technical effect where a casing has an air lock drawer that allows for the introduction of elements into the casing without contaminating the interior space.

Problems solved by technology

However, the installation described in the document DE 851 240 is not suitable for repairing a pod.
Moreover, many users of pods do not have white rooms available.
Such a return is costly both in terms of money and time.
However, the cost of spare parts is very high because the front section of a pod is an expensive item.

first embodiment

[0112]In a first embodiment, the gas supply device 22 comprises a motorised fan blower with filter 58 and one connecting pipe 62 for connecting the gas supply device 22 to the casing 14.

[0113]The motorised fan blower with filter 58 is capable of collecting the ambient air found on the exterior of the bubble 18, filtering it and injecting the filtered air into the interior space formed by the casing 14 and the bubble 18.

[0114]The motorised fan blower with filter 58 is capable of generating a flow of air the particulate concentration of which is controlled.

[0115]The motorised fan blower with filter 58 comprises a fan 66 coupled with a filter 70 and a motor 78.

[0116]The fan 66 enables the generation of a wind or an artificial air current from the ambient air.

[0117]The filter 70 provides the ability to filter particles such as dust particles present in the air in a manner such that the air injected by the gas supply device 22 into the interior space formed by the casing 14 and the bubbl...

second embodiment

[0120]In a second embodiment, the gas supply device 22 comprises pressurised canisters, not represented in the FIGURE. Such pressurised canisters contain a pressurised gas such as nitrogen and are capable of supplying the casing 14, and thus the interior space formed by the casing 14 and the bubble 18 with pressurised gas.

[0121]The pressurised canisters are capable of generating a gas, such as nitrogen, with the particulate concentration thereof being controlled. For example, the gas generated by the pressurised canisters is in conformity with class 6 or class 7 of the ISO 14644-1 standard.

[0122]The pressure switch 26 is connected, on the one hand, to the gas supply device 22 and, on the other hand, to the casing 14.

[0123]The pressure switch 26 is a differential pressure switch. Such a differential pressure switch 26 is able to measure differential pressure, that is to say, a pressure difference between two pressures. The differential pressure switch 26 is in particular, capable of ...

Abstract

Disclosed is a repair unit (10) for a pod (11), especially a laser designation pod, including: a transportable casing (14); a bubble (18) attached to the casing (14), having a retracted state and a deployed state, the bubble (18) including an opening (46) for inserting part of a pod (11) and at least two projections forming tubes (50) for the hands of an operator, each tube (50) opening up in the bubble (18); and a gas supply device (22) for switching the bubble (18) front the retracted state to the deployed state. The casing (14) and the bubble (18) define an inner space sealed from outside pollutants in both the retracted state and in the deployed state.

Description

BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention relates to a repair unit for repairing a pod, in particular a laser designation pod.[0002]A nacelle or pod is a container that is fitted under a carrier in order to carry on board various different devices such as, for example, cameras, infrared imagers or even laser designators.[0003]The repair of the front sections of the pods, especially of the laser designation pods, is carried out in a white room.[0004]A white room or clean room is, according to the ISO 14644-1 standard, a room or a series of rooms where the concentration of particles is controlled in order to minimise, in particular, the introduction, generation and retention of particles within the interior of the white room. Parameters such as the temperature, the moisture and the relative pressure may also be maintained at a specific level in a white room.Description of the Related Art[0005]An installation to be used for performing surgical interve...
